3 Terms and definitions

The terms and definitions defined by GB/T 6809.1 to GB/T 6809.9, and GB/T 26989 are applicable to this document.

4 Disassembly, classification, and cleaning

4.1 Disassembly

4.1.1 The engine shall be completely disassembled to facilitate further classified disassembly and remanufacturing.

4.1.2 The disassembly of the engine shall comply with the provisions of GB/T 28675.

4.1.3 At the time of disassembly, it is initially determined whether the main parts are suitable for remanufacturing.

5 Testing and repair

5.4.5 The repaired crankshaft shall be tested for dynamic balance.

5.5 Camshaft assembly

5.5.1 TEST the damage of the camshaft. MEASURE the coaxiality of each journal, size and abrasion loss of the journal. CHECK the cam profile.

5.5.2 TEST the camshaft follower surface.

5.6 Connecting rod

5.6.1 TEST the big-end bearing seat for damage. MEASURE the cylindricity.

5.6.2 TEST the connecting rod binding surface. The oil duct is deburred and thoroughly cleaned.

5.6.3 TEST the degree of parallelism and torsion resistance of the connecting rod. When the degree of parallelism and torsion resistance are out of tolerance and not greater than 2 times the tolerance, it is allowed to restore the original accuracy by means of straightening. Flaw detection shall be carried out after straightening.

5.6.4 ENSURE that the dimensions of the bushing seat are within the specified limits. Small-end bushing is repaired or new parts are used so that the clearance between the piston pin and the bushing satisfies the corresponding performance requirements of the original product.

5.6.5 Connecting rods are grouped by weight as required, except for powder metallurgy connecting rods.

5.7 Oil pump

5.7.1 TEST the internal damage to the oil pump. MEASURE the clearance between the rotor and the pump body. DISASSEMBLE and CLEAN the safety valve. All parts with indeterminate performance shall be repaired or replaced with new ones.

5.7.2 TEST the performance of the oil pump.

5.8 Water pump

5.8.1 TEST the performance of the water pump. REMOVE internal scale and rust.

5.8.2 TEST the impeller of the water pump.

5.8.3 TEST the airtightness of the water pump.

5.8.4 TEST other parts of the water pump, such as water pump shaft.

6 Assembly

6.1 Before assembly, CLEAN the cylinder block, cylinder head, crankshaft, camshaft, connecting rod and other related parts, so as to ensure that the assembly components meet the product cleanliness requirements.

6.2 The remanufactured engine assembly shall comply with the provisions of GB/T 28679.

6.4 In accordance with relevant national regulations, the remanufactured engine number shall be reprinted on the cylinder block, and the remanufactured product mark is indicated on the engine.

6.3 PAY attention to the assembly sequence of the fasteners when

The tightening torque meets the remanufacturer's design requirements. When assembling, TEST the fit clearance of the remanufactured engine, projection height at the top dead center of the piston, valve timing, fuel supply advance angle, valve clearance, crankshaft axial clearance, selection of connecting rod grouping, etc.

7 Remanufactured engine performance requirements

7.1 The airtightness is in good condition, with no water leakage, oil leakage, or air leakage.

7.2 The starting performance shall be tested in accordance with the GB/T 18297, and in compliance with the requirements for the prototype product.

7.3 The fluctuation rate at low idle speed shall not be greater than 5%. The test shall be carried out according to GB/T 18297, and shall meet the requirements for the prototype product.

7.4 The allowable error of the fuel consumption rate at rated power shall be tested in accordance with the requirements of GB/T 18297, and shall meet the requirements for the prototype product.

7.5 The maximum net power tolerance and the maximum net torque tolerance shall be tested in accordance with GB/T 17692, and shall meet the requirements for the prototype product.

7.6 The minimum fuel consumption rate tolerance for total power test shall be tested in accordance with GB/T 18297, and shall meet the requirements for the prototype product.

7.7 The steady-state speed governing rate shall comply with the remanufacturer's provisions. […]
